I stayed for 5 nights while attending a convention at Music City. Staff were all great, I checked in after a very long journey from Sydney and as SPG gold was upgraded to the top floor. Had access to the exec lounge which served a nice breakfast and had canapes/ drinks for a few hours each evening.
My room was spacious, renovated and I liked the new design. Didn't hear any noise from other guests, which was nice (there a re a lot of bachelorette parties in this town!), but the air conditioning was about the loudest I've ever heard in a hotel.
The Sheraton is a few blocks away from the action on Broadway and Second Ave, but it is not far to walk and there is a free shuttle. The setting across the road form the capitol building is actually pretty nice.
